Title: Wiring board made of ceramic and method of manufacturing the same
Inventor: NAKAJIMA CHIZUO
IPC: H05K3/00
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent fusing of a break groove at the time of baking in a method for manufacturing a wiring board made of ceramic having a metallized layer provided on the periphery of its main surface by baking an unbaked ceramic large plate having a metallizing paste printed thereon along the break groove provided in the peripheral part thereof and breaking the baked plate. SOLUTION: The baking shrinkage factor of a metallizing paste 25 to be printed on a substrate part 21 along the break groove 22 provided to the periphery of the substrate part 21 is made larger than that of a ceramic green sheet. Since the break groove receives expanding action in its width direction by the difference in baking shrinkage factor, the fusing of the break groove is prevented.

IPC: H04W72/08
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To enhance speech quality by measuring a carrier/noise ratio CN of an allocated channel so as to make a re-request of a link channel thereby avoiding the bit error rate BER from being deteriorated. SOLUTION: A signal level Sb of a control channel from a base station is stored in the step S1, a CN (ΔS) is measured in the S11 by using the Sb and a carrier sense level Sa of the link channel, and when a sufficient CN cannot be obtained in the S12, a link channel setup re-request is made. For example, when a disturbing radio wave with 40 dB μV or below equivalent to a 2nd level of the STD-28 is received and a normal signal level of an assigned channel is close to the 2nd level, it is discriminated that the sufficient CN cannot be obtained and a link channel setup re-request is made.

Title: Manufacture of magnetic recording medium
Inventor: HOTTA NOBUHIDE
IPC: G11B5/84
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of scratches in polishing by executing polishing after a specified time or more elapse after forming a protective layer when the surface of the protective layer is polished after a substrate, a magnetic layer and the protective layer are successively formed on a base. SOLUTION: The surface of a protective layer is polished after one hour or more, preferably two hours or more, elapse after forming the protective layer. Although the number of generation of scratches in polishing is reduced as a time after forming the protective layer, the degree of reduction is rapid at first, becomes slow in a short time and settles into a fixed value. Therefore, polishing is preferable after a state of the surface is stabilized by leaving the protective layer as it is for a long time as much as possible. However, from a viewpoint of production in a factory, the elapse of 1-5 hours, preferably 2-4 hours, from forming of the protective layer to polishing is set. And a lubricant is imparted to the protective layer after polishing to form a lubricant layer.
